A special coil is placed near the metallic workpiece, replacing the pusher in traditional forming. When the system releases its intense magnetic pulse, the coil generates a magnetic field which in turn accelerates the workpiece to hyper speed [quantify] and onto the die. The magnetic pulse and the extreme deformation speed transforms the metal ...
An electromagnetic pulse (EMP), also referred to as a transient electromagnetic disturbance (TED), is a brief burst of electromagnetic energy. The origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a conducted electric current.
Magnetic pulse welding started [clarification needed] in the early 1970s, when the automotive industry began to use solid state welding. [citation needed] The primary advantage of using magnetic pulse welding is that the formation of brittle intermetallic phases is avoided, allowing the joining of metals which cannot be effectively joined by ...
The magnetizing pulse is applied for 0.5 seconds, during which the operator washes the workpiece with the particle, stopping before the magnetic pulse is completed. Failure to stop prior to end of the magnetic pulse will wash away indications.
The magnetic field (B, green) is directed down through the plate. The Lorentz force of the magnetic field on the electrons in the metal induces a sideways current under the magnet. The magnetic field, acting on the sideways moving electrons, creates a Lorentz force opposite to the velocity of the sheet, which acts as a drag force on the sheet.
Therefore by applying brief pulses of current, with time between the pulses to allow the heat to dissipate, stronger currents can be used and thus stronger magnetic fields can be generated. The magnetic field produced by pulsed field magnets can reach between 50 and 100 T , and lasts several tens of milliseconds.

At Westinghouse, he was responsible for the development of magnetic pulse welding machines. The magnetic pulse welding process was successful in producing welds within advanced stainless steel fuel pin rods for the Fast Flux Test Facility reactor. He later represented Westinghouse Hanford taking the magnetic pulse welding process to Japan, his ...
